Dispatchable calls.

Each variant of this enum maps to a dispatchable function from the associated module.

Variants

fill_block(Perbill)

A dispatch that will fill the block weight up to the given ratio.

remark(Vec<u8>)

Make some on-chain remark.

• O(1)
• Base Weight: 0.665 µs, independent of remark length.
• No DB operations.

set_heap_pages(u64)

Set the number of pages in the WebAssembly environment's heap.

• O(1)
• 1 storage write.
• Base Weight: 1.405 µs
• 1 write to HEAP_PAGES

set_code(Vec<u8>)

Set the new runtime code.

• O(C + S) where C length of code and S complexity of can_set_code
• 1 storage write (codec O(C)).
• 1 call to can_set_code: O(S) (calls sp_io::misc::runtime_version which is expensive).
• 1 event. The weight of this function is dependent on the runtime, but generally this is very expensive. We will treat this as a full block.

set_code_without_checks(Vec<u8>)

Set the new runtime code without doing any checks of the given code.

• O(C) where C length of code
• 1 storage write (codec O(C)).
• 1 event. The weight of this function is dependent on the runtime. We will treat this as a full block.

set_changes_trie_config(Option<ChangesTrieConfiguration>)

Set the new changes trie configuration.

• O(1)
• 1 storage write or delete (codec O(1)).
• 1 call to deposit_log: Uses append API, so O(1)
• Base Weight: 7.218 µs
• DB Weight:
  • Writes: Changes Trie, System Digest

set_storage(Vec<KeyValue>)

Set some items of storage.

• O(I) where I length of items
• I storage writes (O(1)).
• Base Weight: 0.568 * i µs
• Writes: Number of items

kill_storage(Vec<Key>)

Kill some items from storage.

• O(IK) where I length of keys and K length of one key
• I storage deletions.
• Base Weight: .378 * i µs
• Writes: Number of items

kill_prefix(Key, u32)

Kill all storage items with a key that starts with the given prefix.

NOTE: We rely on the Root origin to provide us the number of subkeys under the prefix we are removing to accurately calculate the weight of this function.

• O(P) where P amount of keys with prefix prefix
• P storage deletions.
• Base Weight: 0.834 * P µs
• Writes: Number of subkeys + 1

suicide()

Kill the sending account, assuming there are no references outstanding and the composite data is equal to its default value.

• O(1)
• 1 storage read and deletion.

Base Weight: 8.626 µs No DB Read or Write operations because caller is already in overlay
